I. Core Structural Features
- Live connection + compression fitting composite connection :The left side is an internal thread live connection (conforming to GB/T 7306), which can be rotated to align with the pipeline during installation; the right side is a compression fitting connection (adaptable to thin-walled metal/plastic pipelines, conforming to GB/T 19228.1 compression connection requirements), which is weld-free, efficient in construction, and combines connection flexibility and sealing performance.
- Soft sealing structure :The valve seat uses EPDM elastic sealing material, conforming to the sealing test requirements of "GB/T 13927 Industrial valves Pressure test", ensuring zero leakage of the medium.
- Miniature handle operation :Equipped with a black engineering plastic miniature handle, conforming to "GB/T 12222 Multi-turn valve drive device connection", 90° rotation can complete opening and closing, small operating torque, suitable for installation in small spaces.
- Brass valve body material :The valve body is made of H59 brass casting (golden appearance), conforming to "GB/T 12225 General valves Copper alloy castings technical conditions", excellent corrosion resistance, suitable for water, gas and other media.

V. Typical Application Scenarios
- HVAC system :Live connection of underfloor heating and radiator pipelines, adaptable to PPR/PE-RT pipelines, facilitating later maintenance and system maintenance.
- Building water supply and drainage engineering :Cold and hot water pipeline branch control, live connection + compression fitting composite connection adapts to different pipe materials (such as copper pipes, stainless steel pipes), flexible and efficient installation.
- Gas pipeline system Indoor gas branch pipe control (must meet the requirements of gas-specific valves), quick-connect structure facilitates gas meter, stove connection and maintenance.
- Solar/Air energy hot water system Hot water pipe quick-connect connection, adapts to the thermal expansion and contraction of the pipe, card sleeve end adapts to thin-walled stainless steel/PPR pipe, ensuring the reliability of system sealing.
